2. Safety instructions

2.1 General safety instructions

This document includes important instructions that should be followed during installation and maintenance of the controller.

Installation and maintenance must only be carried out by authorised personnel, and always in accordance with all applicable stateand local electrical codes. Efficient and safe operation of the controller can be acquired only if the equipment is correctly operated,configured and maintained.

The following notations found in this document can indicate potentially hazardous conditions to the operator, service personnel orthe equipment.

NOTE Highlights an essential element of a procedure to ensure correctness.

CAUTIONIndicates a procedure or practice, which could result in damage or destruction of equipment, if not strictly observed.

WARNINGIndicates a procedure or practice, which could result in injuring personnel or loss of life, if not followed correctly.

2.2 Electrical safety

• Electric shock can cause severe personal injury or death.• Ensure that the genset is grounded before performing any installation or service.• Generators produce high electrical voltages, and direct contact with it can cause fatal electrical shock. Prevent contact with

terminals, bare wires, connections, etc., while the generator and related equipment are running. Do not tamper with interlocks.• To handle the maximum electrical current, the wires used for electrical connections and wirings must be of appropriate size.

2.3 In operation safety

• Before installing the controller, ensure that all power voltage supplies are positively turned off at the source. Disconnect thegenerator’s battery cables and remove the panel fuse to prevent accidental start up. Disconnect the cable from the battery post,indicated by a NEGATIVE, NEG, or (–) first. Reconnect the negative cable last. Failure to do so will result in hazardous andpossibly fatal electrical shock.

• Remove the electric power supply before removing the controller or touching other electrical parts.• Use extreme caution when working on electrical components. High voltage can cause injury or death.• With floors of metal or concrete, use rubber insulation mats placed on dry wood platforms when working near the generator or

other electrical equipment.• Do not wear damp clothing (particularly wet shoes) or allow skin surface to be damp when handling electrical equipment.• Do not operate any electrical device or wires while standing in water, while barefoot, or while hands or feet are wet. It may result

in severe electrical shock.• Do not wear jewellery. Jewellery can cause a short circuit within electrical contacts and cause shock or burning.

In case of an accident caused by electric shock, immediately shut down the electrical power source. If this is not possible, try torelease the victim from the live conductor. Avoid direct contact with the victim. Use a non-conducting object (for example a rope or awooden stick) to release the victim from the live conductor. If the victim is unconscious, apply first aid and get immediate medicalhelp.

Excitation PWM (power limited to 3 W, 12 V/250 mA)

Accuracy ±1 % of full scale


The charge fail is a combined input and output terminal. When the genset starts, the terminal provides controlled power output toexcite the charging alternator. After the excitation is successfully done, the controller reads the charging alternator's output voltagefor monitoring its health. The action for charge fail is configurable.

3.8 Sensor common point


Controller terminal 41

Range ±2 V

Accuracy ±2 % of full scale

NOTE The sensor common point (SCP) terminal 41 of the controller should be directly connected to an electrically sound point onthe engine body. This point on the engine body should serve as a common reference point for all analogue sensors such asthose for measuring lube oil pressure, engine temperature and fuel level. The electrical cable used for the connectionshould not be shared with any other electrical connection. Such a wiring practice is strongly recommended to ensure thatthere is negligible potential difference, if any, between the engine body and the controller's SCP terminal, and, predictableand accurate analogue sensor measurements are always available in a wide variety of field conditions.

7. Running modes

7.1 Remote start/stop mode

To use the Remote start/stop mode, configure one of the digital input as Remote start/stop (Latched type input) and set thecontrollerto Auto mode.

To start or stop the genset while in Remote start/stop mode, activate/deactivate (continuous signal) the pre-configured Remote start/stop input. The controller latches the genset contactor when the controller confirms that all the engine and genset parameters arewithin the configured thresholds. When the pre-configured input is deactivated the controller opens the genset contactor.


7.2 Deep sleep mode

Deep sleep mode is a useful feature to prolong the battery life. In this mode, normal functions of the controller are suspended andthe controller is placed in its lowest power consumption state. The controller maintains the status and alarms it had before Deepsleep mode. When the controller wakes up, normal operations are resumed automatically.

The controller goes in Deep sleep mode when there is no user interaction for the preset Deep sleep mode delay. In Auto mode, ifRemote start/stop is configured to a digital input, the controller wakes up after receiving a Remote start command.

Press and hold any key for at least one second to come out of Deep sleep mode.

7.3 Manual mode

• Inputs: Stop pressed, Start pressed, Simulate start, Simulate stop, Estop, Electric trip, Shutdown, Warning, LLOP, Auto loadtransfer.

• Outputs: flag_start, flag_stop.


8. Alarms

8.1 Alarms

With SGC 110 it is possible to configure several Shutdown/Electrical trip, Warning and Notification alarms, for example Low oilpressure shutdown, Overload warning, and more.

An alarm occurs when a pre-configured parameter is out of the preset level. The Alarm LED flashes and the Sounder alarmactivates (if configured). The controller shows the alarm names on the Alarms display and the nature of alarm on Engine statusdisplay.

To acknowledge the alarms, press the Up and Down buttons simultaneously.

All the alarms are activated at the end of Safety monitoring timer. The controller will not send the start command if Warning,Electrical trip or Shutdown alarms are left unacknowledged.

Alarm typesNo. Alarm actions Description

1 Shutdown Load is taken off from the genset and the genset is immediately stopped by skipping theEngine cooling time.

2 Electrical trip Load is taken off from the genset, the Engine cooling timer begins, after which the gensetis stopped.

3 Warning Warning alarms draw the operator's attention to an undesirable condition without affectingthe genset's operation.The genset cannot be started without acknowledging the Warning alarms

4 Notification The controller shows the message on the display. The genset start/stop operation is notaffected.

9.1 Troubleshooting

This section explains the common faults, their possible causes and remedial actions.

General troubleshootingFault Action

The controller does not power ON.

• Check the battery voltage.• Check the fuse on the battery supply.• Check continuity between battery positive and controller terminal 2.• Check continuity between battery ground and controller terminal 1.

The controller display freezes or hangsup. • Reset the controller power.

The controller fails to crank-start theengine.

• Check the battery voltage.• Enter the Configuration mode in the controller and verify the configuration for the

Start output. Check that the Start output is working correctly by measuring itsoutput voltage.

• Enter the Configuration mode in the controller and verify the configuration of theCrank disconnect method.
